I understand what you are saying. But I have a problem with the whole idea. There will be a real person on the other end. A person who could get hurt by your experiment. You could meet someone who really grows fond of you and wants more.
I'm an introvert as well in a long distance relationship.My boyfriend and I have been together for at least 2 years and a few months.It is hard but we are trying to make it through.He only lives a few hours away from me.We try to meet up as much as possible.
